This invention relates to vimproven'ients in flushing means for coffee boilers.y l

The principal object of this invention' is tol provide means for flushing the interior of a coffee boiler, for the purpose of cleaning the same and disposing of the grounds incident to the boiling of the coffee.

Another object of my invention is to provide simple means for accomplishing this purpose.

A further object of this invention is to provide a device which is simple in c onstruetion,neat in appearance, and economical to manufacture.

A still further object is to provide a device whereby the coffee grounds will be disposed of in such a manner that they will not clog the apparatus.

Other objects and advantages will be a1- parent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure I is a vertical cross-section of my device, Y

Figure II is a fragmentary detail view showing the modified form of fiushing valve, and

Figure III is a cross-section taken line '3 3 of Figure I.

A common method of making coffee is to place the coffee in a bag and'to then pour hot water through the coffee so positioned. The resultant fusion is lthen maintained at a desired temperature in the coffee urn. This method necessitates the frequent change of the cloth bag 'and at `the same time is conducive of a structure which is very difficult to clean.

The average coffee urn found in restaurants and the like, is seldom efficiently cleaned due to its const-ant use. I have on the therefore provided a coffee making device wherein the made'coifee may be withdrawn to a second receptacle, after which the interior of the first receptacle in which the coffee is made, may be thoroughly cleaned previous to making subsequent coffee.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred example of my invention, the numeral 5 designates a counter upon which a receptacle 6 is positioned. This receptacle is adapted to have previously made coffee rests upon a valve seat 14 formed' adjacent the juncture between the receptacle 11 and the tubular portion 12. This valve 13 is carried upon the forked extremities 16 and 17 of a pipe 18. The forkedextremities 16 and v17 form jets as will be later seen. The pipe 18 passes through a stuffing box` 19 which is formed upon the end of a. pipe 21 which is connected to the ordinary water pipes of the building in which the device is located. i f

A valve 22 is positioned within the pipe 21 and is rotated through the medium of a handle23. This handle has an offsetl lever 24 which is connected by a link 26 to` an arm 27 secured to the pipe 18.

The result of this construction is that when the vhandle 23 is turned, water from the pipe 21 will pass through the valve 22 and through the pipe 18 to the `jets 16 and 17. As these jets extend through the valve 13, the water issuing `therefrom will forcibly contact the sides of the receptacle'll. At the same time, the turning of the handle 23 will cause the pipe 18 to move upwardly through the action of the offset lever`24,

link 26 and arm 27. Consequently, the valve 13 will be raised to the dotted line positionV of Figure I. A

This opening of the valve will permit any liquid .within the vessel to be discharged into the tubular member 12, from which point it will empty into a refuse can 28.

At 29, I have shown agitator arms which are carried upon a shaft 31, which shaft is adapted to be driven by a motor 32. This motor may be operated in any convenient manner, as by electricity or a spring.

In order to heat the liquid within the receptacle 11, I provide a heating element 33 which is connected by wires 34 to a pose of which is to draw otl' the coffee fusion into the receptacle (3.

The numeral il designates a hinged door through which a faucet 42 extends. "his hinged door permits the coffee grounds to be placed witl in the receptacle and also permits the water necessary 'for the fusion, to be placed therein.`

It is therefore apparent that by placing water and collec grounds within the receptacle 1l, and by rotating' the arms 2) trie entire mixture will. receive an even cooking by means of the heat derived from the heating element lVhen the coffee fusion has been complot ed, the same drawn olf into the lower receptacle and then by operating the handle 33, the flushing action will take place as before described, thus leaving an absolutely clean `receptacle in which further coffee fusions may be made. Y

In the modilied forni shown in Figure II, the same construction is employed with the exception that a liat valve is used as indicated at 43, which is positioned upon a tubularmeniher 44- having drainage slots 4G therein. These slots are of ample size to accomn'iodate the coitee grounds` It is to be understood that the forms o1" my invention, herewith shown and Vdescribed are to be taken as preferred examples otV the saine, and that various changes relative to the shape, material, size and arrangement of parts may be resorted to without departing from the spirit ot the invention or the scope of the subjoined claims.

Having thus described my invention, I

claim 1. In a flushing device of the character described, a receptacle, a tubular portion secured to said receptacle, a valve seat formed at the juncture ot' said receptacle and said tubular portieri, a valve adapted to rest upon said seat, diverging pipes extending through said valve and forming jets, a pipe extendA ing downwardly from said valve and coininunicating to said diverging pipes, a supply pipe slidahly connected t0 said'last mentioned pipe, a valve positioned within said supply pipe, means l'or simultaneously rotating said valve in said supply pipe, and raising said ir'st mentioned valve from yits seat.

2. In a flushing device, a receptacle having downwardly extending tubularv por'- tion, a valve interposed between said receptacle andl said tubular portion, a pipe extending through said valve so as to form a nozzle, a verticallydisposed pipe secured to said last mentioned pipe, a supply pipe slidably secured to said downwardly extending pipe and communicating therewith, a valve rotatably positioned in said supply pipe, a handle tor rotating said valve, an ollset lever formed on said handle, a link secured to said lever,l an arm secured to said downwardly extending pipe and to said link, for the purpose specified.

In testimony whereof I 'affix my signature. Y
